Range

In Maths¹, the range of a function is the set of all possible outputs within the Codomain. This might be smaller than the codomain itself if the function is not injective.

  • A function in mathematics¹ is a relation between a value in a domain and a value in a codomain across a range. In programming terms, this means that mathematical functions are single-arity and pure. In other words, they take a single value and, given the same value, always produce the same output.
• Codomain
  • In Maths¹, the codomain of a function is the set to which it's output belongs. The exact set of a functions output is known as its range.
